A Comparative Study on the Performance of Optimized Computer Software Packages for GNSS Post-Processing Measurements

With the rapid development of various software for processing data, it is essential to determine the most efficient and dependable use of existing processing software for Global Navigation Satellite System (GNSS) post-processing. This study compares different software packages used for post-processing GNSS measurements in a static mode. The research involved collecting data from dual-frequency GLONASS/GPS receivers at 15 IGS stations, recorded with a 30-second observation interval. The data sets were processed using industry-standard software packages, such as GNSS Solutions, Waypoint GrafNav, Magnet Office Tools, Leica Geo Office, Justin, and Trimble Business Center. All data sets were processed under standardized conditions, and positioning performance was evaluated using a PPP-derived reference solution. Statistical metrics, including mean error, standard deviation, and root mean square error, were calculated for horizontal and vertical components. The results confirm that Waypoint GrafNav and Magnet Office Tools provided better results for horizontal coordinate determination, while GNSS Solutions performed better in establishing point heights. This study underscores the importance of choosing the right software and processing methodology to attain an accuracy of centimeters when making multi-GNSS static measurements. Such insights have practical implications for engineers and surveyors in making informed decisions on the choice of post-processing software.
